When I start my Moto G2 (XT1038) from cold, the entire boot animation plays and the home screen shows and the phone works fine. The moment the phone is locked and I press the power button to turn the screen on and entire my pin, the area near the microphone heats up rapidly to a point where I can not touch the spot for more than a few seconds. The screen stays blank though. After a few minutes of inactivity the area cools down. But if I try to turn the screen on the same thing happens. Meanwhile, I can hear the alarms I have set in my phone, go off at designated times, can hear the incoming phone call rings, SMS / message notifications, etc. But cannot get the screen to come on after the initial bootup. Can not turn off the phone either, same thing happens. Battery lasts as usual. No heating issues while charging. Any ideas why this might be happening? It is running Marshmellow at the moment, and the update happened many weeks before this issue. Auto-updates are turned off.
Not sure if I need to replace the display or battery or some other hardware.

when I try to start the phone the following occur:
the display light turns on, shortly after that the phone emits that startup vibration, the backlight remains on for aprox. 85 seconds then the phone aparently shuts down. that meant, the backlight of the display turns off.
problem history:
I was at work and as usual i was listenin to music via handsfree. while my phone was in poket it seemed that somehow my poket pressed the sleep button and turned the screen up. no prob here. i got the phone out of ma poket. reverted the volume @ maximum and then locked the phone and turned the screen off and putted back in pocket. after some time i wanted to change the song. got out the phone, turned on the screen but nothink apeared except a horizontal line in the middle of the screen. I tried to shut down/up the screen but nothink apeared. after a couple of tries the screen turn on but it was unusual what i saw on it. I saw a sketch of the energy rom home screen with diferent colors.
Meantime i was tryng to get the screen outta sleep the music still played in the phones.
I thaugt that a reset will do but it didn't. got out the battery and got home. reasembled it, powerd up the phone and voila! the phone started up normaly. got out the battery, introduced the sim card. powerer up the phone but bad luck. the happiness was short lived. the problem camed back. another thing i noticed is that when i powwer on the phone i let it on but it wont output that energy rom bootup sound.
Can someone elude me with whats the problem with my phone?
hope I was clear enough!
Have a great day/night!
UPDATE: LEFT IT OVERNIGHT WITHOUT THE BATTERY AND NOW ASSEMBLED BACK. IT'S WORKING BUT I THINK IF I GIVE A RESTART THE problem will come back.
I noticed that if i leave the screen on (with gravitybox) for a mid-long period, e.g. 30/60 min, the display will start flickering (or jumping) and the oscillation will increase with time. The only solution is to turn off the phone and let it rest for some time then power it on. Do you know why?

I am not sure if mine is related, but today my Nexus 5's screen flickered then went black. I can feel the phone vibrate when holding the power button down. But still nothing, tried plugging into computer and after unplugging I hear the low power chime. So I know that it is working aside from the screen staying black.
The phone is running 4.4.3 stock that I flashed via twrp, with faux123 18u kernel, exposed installer, gravity box. This could all be coincidence, and I could just have a bad screen. But does anyone have any suggestions?
My phone just arrived. I've plugged it in to make sure it's alive, it stated low battery so I've unplugged it and moved elsewhere. Now ever since I plugged it back in, it vibrates, constantly. It even plays vibrates over the top of it's constant buzz. It operates perfectly fine otherwise, it boots and I've set up my google account. Just curious if there was a way to solve this besides waiting out the battery.
Edit: smothering the power button to force it to turn off, even when it refuses to turn on due to lack of battery or even show anything on screen does stop the vibration. Guess it's a faulty device or something :/ *sigh*
Turns out that as soon as it vibrates it continuously vibrates at a low mode forever. So it can be fine until you plug in a charger, or receive a notification, then it's back to perma vibrate.
I have a sprint Nexus S 4g. It recently got wet and i let it dry out for a day. The screen is slightly cracked, but before getting wet, the screen still worked properly. Currently, my phone will turn on and i can confirm this through the use of droidscreen, which displays the screen. Using adb, i can still input taps but the screen remains black. Even though the screen is black, the screen still registers touches and i can still open apps, open the notification bar, etc. I let the battery die recently. When i started charging again, it displayed the charging animation when off. I turned it on, and it did not show the boot animation, but the screen turned on at the home screen (since i do not use a lockscreen, and i mostly use this device for a hotspot). The power was at 1%, so i let it charge. When i came back to it a few minutes later, the screen no longer worked again. I have been able to recreate this and i do not know why the screen only displays at around 1%, but still registers touch at any time. Could replacing the screen fix this issue or is this a result of water damage in the circuitry?
This device is rooted and is currently on CM.
All of a sudden my phone started rebooting on its own. Then while using it started to vibrate for like 10 seconds until I removed the battery. Then I turned it on and on the home screen it stuck. I had to pull out the battery. and since then it wont turn on! When i push the power button it vibrates like it does on the startup but theres no display. Two times in the process, " battery too low to turn on" message has been displayed & nothing else! same vibrates at startup and no display problem. HELP
